Extracted disturbances from the clinical image sequence, for the longitudinal direction (a), radial direction (b), and rotation angle (c). The disturbance obtained by the BM (blue), PM (cyan), SBM (magenta), SPM (yellow), SWBM (green) SWOM (gray), SWPM (orange), and SWPOM (black) methods is demonstrated.
